DIRTT (DRTTF) CTO Adrian Zarate Receives Award

What Happened

Adrian Raul Zarate, Chief Transformation Officer and Director of DIRTT Environmental Solutions Ltd. (DRTTF), was granted 31,650 deferred share units (DSUs) on 2026-03-31. The filing reports an economic value of $0.55 per unit, totaling $17,408 (derivative award).
This transaction is an award/grant (code A) of DSUs — a form of deferred compensation — not an open-market purchase or sale of common shares.

Key Details

Transaction date: 2026-03-31; Form 4 filed 2026-04-02 (reporting period 2026-03-31).
Award size: 31,650 DSUs; reported value: $17,408 (US$0.55 per unit).
Pricing basis: DSU count was calculated using the issuer’s TSX closing price C$0.77 on March 30, 2026 and converted using Bank of Canada rate C$1.3926 = US$1.00 (per filing footnote).
Shares owned after transaction: not specified in the filing.
Footnotes: DSUs are the economic equivalent of one common share and are derivative awards that settle in common shares or cash after the holder’s termination of service. For U.S.-taxed directors, settlement occurs no later than 40 days after termination and is calculated based on a post-separation closing price (see filing footnote).

Context

DSUs are deferred compensation that convert to shares or cash at a future separation date; they do not represent immediate tradable common shares.
This is an award (routine compensation) rather than a market purchase or sale, so it signals compensation policy more than an insider trading view.

Footnotes (2)

[F1]Each deferred share unit ("DSU") was granted pursuant to the DIRTT Environmental Solutions Ltd. Third Amended and Restated Long Term Incentive Plan and is the economic equivalent of one common share (a "Common Share") of DIRTT Environmental Solutions Ltd. (the "Issuer"). All DSUs settle following the cessation of service and employment with the Issuer (the "Termination Date"). For directors who are subject to taxation in the United States ("US Directors"), the DSUs will settle no later than forty days following the Termination Date. Each DSU will be settled in one Common Share or in the cash equivalent of such Common Shares, calculated based on the closing price of the Common Shares on the day prior to the 30th day following separation from service for US Directors.
[F2]The price used to calculate the number of DSUs granted was C$0.77, which was the closing price Issuer's Common Shares as reported on the Toronto Stock Exchange on March 30, 2026. The price was converted using the Bank of Canada exchange rate for March 30, 2026 of C$1.3926 = US$1.00.
